资源简介:
Sarqardleq Fjord is part of a tidewater glacier-fjord system in western Greenland. These velocity observations were collected as part of a field program to study the dynamics of the ice/ocean boundary layer of a medium-sized glacier. The glacier's margins are characterized by turbulent plumes fed by subglacial discharge, as well as broader, quiescent regions characterized by submarine melt. Ocean property and velocity data were collected to characterize the spatial and temporal variability of the near-ice dynamics. The current velocity profiles were collected by an 300 kilohertz (kHz) RDI Acoustic Doppler Current Profiler (ADCP) deployed on a mooring at ~120 meter (m) depth. The velocity bins extend from 106m to 2m and have a width of 4m. The mooring was deployed from July 18, 2012 to April 15, 2013. It was located ~1.6 kilometers (km) from the glacier terminus.
萨夸德莱克峡湾(Sarqardleq Fjord)是格陵兰西部潮水冰川峡湾系统的组成部分。本次流速观测作为野外科考项目的一部分开展,旨在研究中型冰川的冰-洋边界层动力学特征。该冰川的冰缘区域以冰下径流补给的湍流羽流为典型特征,同时存在以海底消融为标志的更广范围的缓流区域。研究人员采集了海洋要素与流速数据,以解析冰区附近动力学过程的时空变异性。本次流速剖面数据由一台300千赫兹(kilohertz, kHz)的RDI声学多普勒流速剖面仪(Acoustic Doppler Current Profiler, ADCP)采集,该设备布放于约120米(meter, m)水深的锚系平台上。流速分层单元的覆盖范围为106米至2米,分层宽度为4米。该锚系平台的布放时段为2012年7月18日至2013年4月15日,其布设位置距冰川末端约1.6千米(kilometer, km)。
